摘要

我们研究了 15 种不同的 Skyrme 相互作用参数，并将它们应用于 N = 78 以外的 Te、Xe、Ba、Ce、Nd、Sm、Gd、Dy、Er 和 Yb 同位素链，在基于密度泛函理论的均场方法中计算理论结合能。计算结果与现有的结合能和四极变形实验数据进行了比较，目的是找出哪种相互作用对这些同位素链的形状和结构研究最为方便。

Microscopic study of ground–state binding energies in Z = 52 − 70 neutron–rich nuclei

We investigate 15 different Skyrme-interaction parametrizations and apply them to the chains of Te, Xe, Ba, Ce, Nd, Sm, Gd, Dy, Er, and Yb isotopes beyond N = 78 to calculate theoretical binding energies within the mean-field approach based on density functional theory. Results of calculations are compared with available experimental data on binding energies and quadrupole deformation with the aim to find out which interaction is the most convenient for shape and structure studies of these isotopic chains.
